Excitation and Ionization Potentials
JEE Main asked Excitation and Ionization Potentials 2 times in 2 of the 108 shifts Lumi analysed, all in 2024. It belongs to Bohr's Atomic Model, in Atoms (Physics). In 2024 it came in more than one shift of the same year.

Questions on this idea a shift, by year
2017–2026. Asked in 2024. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Physics questions.
Raw count: 2017: 0 in 1 shift · 2020: 0 in 12 shifts · 2021: 0 in 24 shifts · 2022: 0 in 24 shifts · 2023: 0 in 12 shifts · 2024: 2 in 18 shifts · 2025: 0 in 8 shifts · 2026: 0 in 9 shifts.
